About the HDMI DA2
The Extron HDMI DA2 distribution amplier distributes one HDMI input signal to two outputs
simultaneously. It is fully High-bandwidth Digital Content Protection (HDCP) compliant.
The HDMI DA2 supports data rates up to 6.75 Gbps (2.25 Gbps per color) with up to 12-bit
deep color and uses the EDID Minder
®
feature for EDID management.
The automatic output compatibility correction feature scans each output device to ensure
that the output signal is compatible with the audio capabilities, color depth, and format
requirements of the device. Each output is adjusted independently.
HDMI DA2 Features
HDMI signal distribution — The HDMI DA2 accepts one HDMI input and provides two
HDMI outputs.
Key Minder
®
— Key Minder authenticates and maintains continuous HDCP encryption
between the input and output devices to enable simultaneous distribution of a single encrypted
source to two displays.
Signal Status LEDs — Front panel signal status LEDs indicate TMDS and HDCP status for the
input and each output.
EDID Minder — This feature allows the user to choose from a list of 46 factory-loaded EDID
les, to import EDID information from either of the display devices, or to import and save
an EDID le from a PC. EDID Minder has two modes of operation that can be selected and
configured using SIS commands:
z Automatic: EDID from the display connected to output 1 is read and stored at the input
automatically (default mode). Use SIS commands to read and store EDID from output 2.
z User assigned: EDID can be manually assigned from the internal factory EDID table,
which contains 46 unique EDID les categorized by native resolution and audio support.
Additionally, there are four user slots available to store and recall EDID from connected
displays.
